The TEA1751LT is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1751LT combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components.

The RT9259A is a dual-channel DC/DC controller specifically designed to deliver high quality power where 12V power source is available. This part consists of a synchronous buck controller and an LDO controller. The synchronous buck controller integrates MOSFET drivers that support 12V+12V bootstrapped voltage for high efficiency power conversion. The bootstrap diode is built in to simplify the circuit design and minimize external part count. The LDO controller drives an external N-MOSFET for lower power requirement.
The RT9228 is a 3-in-one power controller optimized for high-performance microprocessor and computer applications. The IC integrates a synchronous buck PWM controller, a linear regulator, and a linear controller as well as monitoring and protection functions into a 24-pin SOP package. The PWM controller regulates the microprocessor core voltage. The linear regulator provides power for the clock driver circuit and the linear controller regulates power for the GTL bus.

The UCC24630 SR controller is a high-performance controller and driver for N-channel MOSFET power devices used for secondary-side synchronous rectification.
The combination of controller and MOSFET emulates a near-ideal diode rectifier. This solution not only directly reduces power dissipation of the rectifier but also reduces primary-side losses as well, due to compounding of efficiency gains.
POWER FACTOR CONTROLLER
This application note presents practical step-by-step design considerations for power supply system employing Fairchild’s FAN6921 PFC/PWM combination controller, which combines a Boundary Conduction Mode (BCM) Power Factor Correction (PFC) controller and QuasiResonant (QR) PWM controller. Figure 1 shows the typical application circuit, where the BCM PFC converter is in the
front end and the Quasi-Resonant flyback converter is in the back end.
